The reaction of furfurylamine with two equivalents of PPh2Cl in the presence of Et3N affords furfuryl-2-(N,N-bis(diphenylphosphino) amine), (Ph2P)2NCH2-C4H3O (1). The corresponding ruthenium(II) complex trans-[Ru((PPh2) 2NCH2-C4H3O)2Cl 2] (3) was synthesized by reacting 1 with [Ru(eta6-p- cymene)(mu-Cl)Cl]2. The reaction of furfurylamine with one equivalent of PPh2Cl gives Ph2PNHCH2-C 4H3O (2). The reaction of 2 with [Ru(eta6-p- cymene)(mu-Cl)Cl]2, [Ru(eta6-benzene)(mu-Cl)Cl] 2, [Rh(mu-Cl)(cod)]2 and [Ir(eta5-C 5Me5)(mu-Cl)Cl]2 yields the complexes [Ru(Ph2PNHCH2-C4H3S) (eta6-p-cymene)Cl2] (4), [Ru(Ph2PNHCH 2-C4H3O)(eta6-benzene)Cl 2] (5), [Rh(Ph2PNHCH2-C4H 3O)(cod)Cl] (6) and [Ir(Ph2PNHCH2-C 4H3O)(eta5-C5Me 5)Cl2] (7), respectively. All the complexes were isolated from the reaction solution and fully characterized by analytical and spectroscopic methods. The structure of [Ru(Ph2PNHCH 2-C4H3O)(eta6-p-cymene)Cl 2] (4) was also determined by single crystal X-ray diffraction. Complexes 3-7 are suitable precursors forming highly active catalysts in the transfer hydrogenation of a variety of simple ketones. Notably, the catalysts obtained by using the ruthenium complexes [Ru(Ph2PNHCH 2-C4H3O)(eta6-p-cymene)Cl 2] (4) and [Ru(Ph2PNHCH2-C4H 3O)(eta6-benzene)Cl2] (5) are much more active in the transfer hydrogenation, converting the carbonyls to the corresponding alcohols in 97-99% yields (TOF ?300 h-1), compared to analogous rhodium and iridium complexes and the trans-Ru(II)-p-cymene bis(phosphino)amine complex.

A series of ruthenium(II)-arene complexes of several bipyridine and phenanthroline derivatives have been synthesized by employing a green and efficient protocol involving water as a solvent under sonication. The structures of all the complexes were elucidated by the spectroscopic analysis. The geometry of the chlorido and PTA (1,3,5-Triaza-7-phosphaadamantane) complexes were further confirmed by DFT and single crystal XRD. The stability study in various solvents, specifically in the intracellular one was conducted. Most of the compounds exhibited significant potency and selectivity against MCF7 and HeLa cell lines with respect to normal HEK-293 cells compared to cisplatin and RAPTA-C (Ruthenium(II)-arene PTA complex). Complex [(eta6-hexamethylbenzene)RuCl(kappa2-N,N-4,4?-di-n-nonyl-2,2?-bpy)]Cl (3e) presented best anticancer profiles against all the human cancer cells. Interestingly, few complexes turned up to be highly fluorescent depicted by the quantum yield values. Remarkably, [(eta6-p-cymene)RuCl(kappa2-N,N-bpy)]Cl (3i) was identified as most significant anticancer theranostic agent interms of potency, selectivity and fluorescence quantum yield. This complex also represented itself as significant cellular imaging agent in live U-87 MG cells which was monitored by confocal microscope. Absorption and emission spectral studies of bypyridine and phenanthroline complex series revealed that the complexes interacted with calf thymus DNA through groove binding as well as intercalative mode. In addition to this, strong binding efficacy of these scaffolds wih BSA (Bovin Serum Albumin) also enhanced their transportation property inside the cells.

The effect of protonation on the spectroscopic properties of Re(I) and Ru(II) complexes with the ligand 11-triphenylamine-dipyrido[3,2-a:2?,3?-c]phenazine (dppz-TAA) are investigated. For [Re(CO)3Cl (dppz-TAA)] protonation with triflic acid in CH2Cl2 results in a depletion of the intraligand charge-transfer transition at 500 nm (epsilon = 17700 M-1 cm-1) and the concomitant grow-in of a band at 780 nm (epsilon = 18200 L mol-1 cm-1). Resonance Raman spectra of the protonated species show a strong band at 1628 cm-1 attributed, through DFT modeling, to a TAA mode with bending of the phenazine NH linkage. The low energy band is also predicted by TD DFT. The behavior of [Ru(bpy)2(dppz-TAA)]Cl2 was studied in aqueous solution as a function of pH. The electronic absorption spectrum shows modest changes as a function of pH. The excited state properties show a short-lived emissive state (lambdamax = 500 nm) that is diminished in intensity at lower pH. The compound also has a long-lived dark state with absorption features at 420 and 700 nm; the lifetime of this state is also pH sensitive varying from 2500 to 500 ns. The dark long-lived state is probed with transient resonance Raman spectroscopy and is assigned as a 3pi; pi? ligand state. This is consistent with DFT studies. From these data the pKa for [Ru(bpy)2(dppz-TAA)]Cl2 is estimated as 4.5.

Ruthenium possesses several favorable properties suited to rational anticancer drug design when conjugation with the porphyrin moiety was accomplished through peripheral pyridyl rings. The ruthenium porphyrin conjugates are soluble at least moderately in aqueous solution and are thus suitable for biological investigations in particular for cytotoxicity and photocyotoxicity tests. In present study the compound 5,10,15,20 tetra pyridyl porphyrin coordinated to four [Ru (bipy)2 Cl]+ groups (meso-5,10,15,20 tetrakis {4(chloro-bis-bipyridyl ruthenium(II)) pyridyl} porphyrin) is synthesized by modified Alder method. This compound is characterized by UV-Visible Spectroscopy, FT-IR Spectroscopy, 1H-NMR spectroscopy, Fluorescence Spectroscopy and Cyclic Voltametry. In-Vitro anticancer activity of the compounds have been evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay method. The results show that the compound is cytotoxic against human lymphoma cancer cells.
